Everything you need to know about the browser cache. Everything you need to know about the browser cache The cache has disappeared from the obb folder

Services and tricks with which you can find EVERYTHING.

Why is this needed: Did you briefly read the article in the morning and decided to take a closer look in the evening, but it’s not on the website? A few years ago you visited a useful site, today you remembered it, but there’s nothing left on the same domain? This has happened to each of us. But there is a way out.

Everything that goes on the Internet is stored there forever. If some information is posted on the Internet for at least a couple of days, there is a high probability that it has become the property of the collective mind. And you will be able to reach her.

Let's talk about simple and publicly available ways to find sites and pages that have been deleted for some reason.

1. Google cache that remembers everything

Google specifically stores the text of all web pages so that people can view them if the site is unavailable. To view the version of the page from the Google cache, type in the address bar:

http://webcache.googleusercontent.com/search?q=cache:http://www.site/

Where http://www.site/ must be replaced with the address of the site you are looking for.

2. Web-archive, which contains the entire history of the Internet

6. Archive.is, for your own cache

If you need to save some web page, you can do this on archive.is without registration and SMS. There is also a global search for all versions of pages ever saved by users of the service..

7. Caches of other search engines, you never know

If Google, Baidu and Yandex did not manage to save anything sensible, but a copy of the page is really needed, then we go to seacrhenginelist.com, go through the search engines and hope for the best (so that some bot visits the site at the right time).

8. Browser cache when all else fails

You can’t view the entire page this way, but pictures and scripts from some sites certain time are stored on your computer. They can be used to search for information. For example, using a picture from the instructions, you can find a similar one on another site. Briefly about the approach to viewing cache files in different browsers:

Safari

Looking for files in a folder ~/Library/Caches/Safari.

Google Chrome

In the address bar we type chrome://cache

Opera

In the address bar we type opera://cache

Mozilla Firefox

Type in the address bar about:cache and find on it the path to the directory with the cache files.

9. Trying to download the page file directly from the server

We go to whoishostingthis.com and find out the address of the server on which the site is or was located:

After that, open the terminal and using the command curl trying to download the required page:

What to do if nothing helps at all

If none of the methods gives results, but find deleted page If you desperately need it, then all you have to do is contact the owner of the site and shake out the treasured information from him. First, you can get through the contacts associated with the site on emailhunter.com:

And about collecting information about people, read the articles and.

When we touched on browser cache in one of our articles about it, I had to take a time out. It turned out that not all modern browsers are so accommodating regarding the placement of the cache and its size according to user requirements. Modern browser fashion believes that the cache should be there and of the size that seems best to the browser itself. However, a solution was found.

1. What is “browser cache”

A cache, in relation to a browser, is a directory with files on the hard drive where the program stores elements of the pages being viewed. For example, drawings and scripts are stored there. When the page is refreshed, the browser will no longer download this data from the Internet, but will simply take it from hard drive, which is accessed at a significantly higher speed than the Internet. Therefore, the browser data caching technology itself is very effective.

However, this technology also has a negative side. The cache folder is located on the system disk. In addition, as a rule, it is created for each user separately - in the user profile. More users in the system means more cache directories. This is bad if the disk capacity is small. Therefore, you can tell the browser a different location for the cache folder (for example, on a second hard drive, or even on external storage).

A secondary goal is to limit the size of the browser cache folder. But you should experiment with this parameter only in severe disk space saving mode!

2. Why you don’t need to clear the cache manually

Many system cleaning utilities are very fond of clearing browser cache folders. Of course, this allows them to show effective results compared, for example, with a built-in disk cleaning program.

Hence, many users have developed the habit of clearing their browser cache almost every day. But this is not only an unnecessary procedure, but also harmful.

2.1. Why manually clearing cache is useless and harmful

As mentioned above, using a cache, the browser speeds up the loading of website pages, which makes working with it more convenient. It is also worth remembering that the cache is automatically updated and cleared if the specified volume is exceeded. That is why cleaning it manually is simply useless. The next day it will appear again and will be exactly the same as the day before. At the same time, it will never exceed the limit specified in the settings.

Moreover, clearing your browser cache daily will slow down page loading in the future. The computer will be forced to download the data that was reserved to speed up page loading again, loading the channel, significantly increasing page loading time and wasting system resources on actions that could not have been performed. As a result, your online experience will suffer.

2.2. In what situations is this still necessary?

But there are situations in which clearing the cache is still necessary. For example, if a site began to display content incorrectly. This happens when the webmaster has changed the template, display styles or site scripts, and the user has old versions of them in the cache. In this case, everything may go wrong and the site will not be displayed correctly. In this case, it is enough to reload the page with the Ctrl-F5 combination and then the browser will update the cache of this particular site, deleting old data and loading new data in its place.

Advice:
Use the Ctrl-F5 combination on your keyboard to refresh the cache only for the site that is open in the current browser tab. This will also save data for other sites.

It is also worth clearing the cache if you visited some sites and would not want any of your work colleagues or family members to find out about it (since data about this site will be recorded in the cache, visit history).

In other cases, there is simply no need to clear the cache, because it is a waste of time. If the cache takes up too much disk space, you can change the limits so that the maximum cache size does not exceed the specified value.

3. We limit the appetites of browsers

3.1. Google Chrome (applicable to other browsers based on the Chromium engine)

Everything turned out to be difficult here. You will need to find the shortcut that you use to launch this browser. Usually most users do this as a shortcut on the desktop or panel quick launch. Open the shortcut properties using the right mouse button and enter the following phrase in the “Object” field after chrome.exe:

--disk-cache-dir=d:chrome_cache --disk-cache-size=104857600

Please note that there are actually two hyphens before the keys, and this is not a typo by the author. The first key specifies the location of the browser cache directory. In the example given, this is drive D and the directory right at the root of the drive. The second key specifies maximum size directory with cache in bytes. Those. if you need to give the browser 100 MB, then you will need 100*1024*1024= 104857600 bytes, as in the example I gave.

How difficult everything is... However, we have already dismantled the most difficult browser. Then things will get easier - all other browsers are quite cooperative.

3.2. Internet Explorer

This browser doesn't hide cache settings too far. The above applies to the latest version of the browser today, number 10. In the settings, open "Browser Options". IN "General" there is a section "Observer's Journal" → "Options" → "Temporary Internet files".

By button "Move" you can send the cache folder to the desired location.

3.3. Mozilla Firefox

As for Firefox, the shortest path to its cache looks like this. In the main menu of the browser we find "Settings", and in it the point "Additional". Now "Net" → "Cached Web Content". Here you can clear your browser cache and limit its size in megabytes.

But setting the location of the cache folder will be a little more difficult. First we write in the address bar about:config. In the window that appears, click on the only button.

The settings window now appears. We are looking for a parameter in it . He most likely won't be there. You will have to create: right mouse button and select from the menu "Add".

Parameter name browser.cache.disk.parent_directory

The value is the path to the folder on the disk.

3.4. Opera 12

In the address bar we write: opera:config

In the settings we find the User Prefs section. Among the parameters we are looking for Cache Directory4. There is no typo with the number 4. In the value we indicate the desired path.

And the cache size and its cleaning are arranged quite civilly. In the normal settings section.

So, today we learned how to limit the size of the browser cache and specify its storage location. But this knowledge should be used wisely. Don't make the cache too small, as this will negate the benefits of page caching. Don't make it too large, as this will waste disk space without improving browser performance. If there is no hard disk space saving mode, then allow the browser to determine the size itself, in otherwise indicate 100-200 MB. Also, to save space on the system partition, you can place the cache folder on another disk or partition.

Each user's transition to Internet sites is saved in Browser History, along with all the details: time of visit and search name. This history is available to the user and can, if necessary, be deleted: both completely and individual searches.
